It is a common trait for tires to become nosier as they wear, some worse than others.
The 17" Yoko Geolanders are some of the worst I've ever experienced this condition with. They were very subdued when they were new. 31,000 miles later, and they absolutely roar. I've been pretty displeased with these tires overall.
Personally, I've been wanting to replace them for a year now, mostly due to the roar, or "road noise". However, my wife wants to squeeze every last mile out of them. She seems inept when it comes to refinement sensibilities.
Road noise is almost always a condition of the tires on the vehicle, and the road surface they are riding on. The variable is how well has the manufacturer isolated the cabin from the tires/road, by means of design or engineering.
